AUTOMATIC WATERING-TROUGH.

Specification of Letters Patent.

Patented Nov. '15, 1910.

Application filed July 8, 1910. Serial No. 571,047.

To all whom it may concern:

Be it known that I, MOORE D. MoDoUGALL, residing at VVatsonville, in thecounty of Santa Cruz and State of California, have invented a new andImproved Automatic Watering-Trough, of which the following is aspecification.

This invention relates to that type of watering troughs or fountains inwhich the supply is automatically out off by the weight of the trough,and in which the feed valve automatically opens and feeds to the troughafter the predetermined or valve closing weight thereof is reduced.

My invention, while readily adapted for watering stock, is moreparticularly intended for watering poultry, the valve mechanism beingespecially designed for releasing the water in drops or very smallquantities.

My invention primarily has for its object to provide a watering means ofthe character stated, of a very simple and economical construction, thatcan be easily set up for use, and which cannot readily get out of order,and the said invention consists in certain details of structure andpeculiar combination of parts, all of which will be hereinafter fullyexplained, specifically pointed out in the appended claims andillustrated in the accompanying drawings, in which:

Figure 1, is a perspective view of my improved construction of wateringtrough. Fig. 2, is a vertical, longitudinal section thereof, the valvebeing shown as held closed by the water loaded trough. Fig. 3, is asimilar view, the valve being to its released or open position. Fig. 4,shows the several parts that constitute my invention as separated. Fig.5, is a detail perspective view of the front end of the watering deviceand shows the hook or clamp for holding the valve closed when the troughis removed or being cleaned.

In the practical arrangement, my invention embodies attachmentsespecially adapted or designed for being removably connected to the endof a water delivery spout or pipe section 1, the outer or dischargingend of yyhich is externally threaded as indicated 2 designates a capthat is internally threaded to fit over and close the discharge end ofthe pipe 1, and the said cap has a small discharging orifice 20 overwhich is mounted a valve seat 3, that is tightly held on a rubber Washer4 also apertured as at 10 for the passage of the valve stem 5, movablethrough the apertures 20 and 10 and having a valve head 50 for engagingthe seat 3, as is clearly shown in Fig. 3.

6 designates a bushing that threads onto the pipe 1 and it is externallythreaded to receive the lateral internally threaded extension 70 of aT-shaped housing 7, in one end of which is threaded a plug 8 verticallyapertured as at 80 for guiding the valve stem 5 that passes through it.The upper end of the valve stem has an eye portion for hanging on a wirespring sustaining arm 9 that extends parallel with the pipe 1 and isbent down at right angles to form a supporting member 90 for connectingwith and being supported by the pipe 1 and the outer or front end of thesaid tension spring 9 terminates in a hook 91 for receiving the hangingbail 92 that supports the watering trough 93, it being obvious from thedrawing that when the trough is full, the tension of spring 9 isovercome and the valve stem 5 is pulled down to hold the valve 50 closedagainst the valve seat to cut off the supply, and when the water is usedfrom the trough to that extent that the tension of spring 9 lifts thetrough the stem 5 is raised and the water feeds through the smalldischarge outlet in the cap until the trough is again filled to thedesired weight to close the valve. To regulate the tension of the arm 9,a slide member 15 engages the said arm and is mounted to slide on thepipe 1, it being held against the bushing 6 by a jam nut 16.

When it is desired to clean or remove the tank, the valve stem is helddown by a hook member 17 that is hung on the arm 9 and has a fingerportion for being swung under the lower end of the T-shaped housing.

From the foregoing, taken in connection with the drawings, theadvantages and the manner of adjustment of my invention will be readilyapparent. The parts are cooperatively so arranged that theirconstruction is simple, inexpensive to manufacture and of compact form,so they may be readily transported without danger of being broken ordisarranged.

Having thus described my invention, what I claim is:

1. In an apparatus of the character stated, the combination with a watersupply pipe, and a closure for the discharge end having a dischargingorifice and a valve seat surrounding the said orifice; of a valve forcooperating With the seat, a spring arm disposed in a plane parallelWith the pipe, a tension regulator mounted on the pipe that engages thespring arm, a stem for the Valve connected to and movable With thespring arm and a Water collecting trough suspended from the spring arm.

2. An apparatus of the character stated, comprising a casing attachableto the discharge end of a Water delivering pipe, a closure cap Withinthe casing for fitting over the discharge end of the water pipe, saidcap having a valve seat, and a discharge through the seat, a trough intoWhich the casing discharges, a valve for cooperating With the seat andthe Water feed, a' tension device mounted on the pipe, and a hanger thatconnects With thesaidtension device, the stem of the controlling valvebeing connected to and movable with the tension device, for the purposesstated. 7 V

3. In an apparatus of the character stated, the combination With a Watersupply pipe, a closure cap removably mounted on the discharge end of thepipe and having a discharge orifice With a surrounding valve seat, aT-shaped casing removably mounted on the pipe to inclose the capped end,an apertured plug in one end of the casing, a valve stem guided throughsaid plug having a valve for cooperating With the valve seat in the capmember, a spring arm disposed in a plane parallel with the pipe andsupported by the pipe, a connection for coupling the valve stem and thesaid arm, a Water receiving trough and a supporting bail for the troughthat hangs from the spring arm.

4:. In an apparatus of the character stated, the combination With aWater supply pipe, a closure cap removably mounted on the discharge endof the pipe and having a discharge orifice with a surrounding valveseat, a T-shaped casing removably mounted on the pipe to inclosethe'capped end, an apertured plug in one end of the casing, a valve stemguided through said plug having a valve for cooperating with the valveseat in the cap member, a spring arm disposed in a plane parallel Withthe pipe andsupported by the pipe, a connection for coupling the valvestem and the said arm, a Water receiving trough and a supporting bailfor the trough that hangs from the spring arm, and

a tension regulator adjustably mounted on the service pipe and connectedWith the spring arm for increasing or diminishing its tension.
